Pseudoparkinsonism is characterized by which symptoms?

Pseudoparkinsonism is a condition that resembles Parkinson's disease and is primarily characterized by symptoms such as tremors, rigidity, bradykinesia (slowness of movement), and impaired gait. These symptoms typically arise as side effects from certain medications, particularly antipsychotics, which block dopamine receptors, leading to a decrease in dopamine activity in the brain. The presence of tremors often manifests as shaking, especially at rest, while impaired gait leads to difficulty in walking, characterized by shuffling or absence of arm swing.

The other options describe symptoms that do not align with the characteristics of pseudoparkinsonism. Excessive energy and movement would be contrary to the reduced movement seen in this condition. Difficulty in breathing is not a hallmark of pseudoparkinsonism and can arise from different medical issues. Severe anxiety attacks are also not related to the motor symptoms characteristic of this movement disorder. Instead, the correct answer highlights the core defining features of pseudoparkinsonism, helping to clarify its relationship with Parkinsonian symptoms caused by medication side effects.
